R0601-825M-02G-N21-SMAFF

Metamag's R0601-825M-02G-N21-SMAFF reflective Auto-Tune Filter® (AtF) is a coaxially packaged adaptive wideband filter well suited for interference mitigation applications that require low power thresholds. The AtF is a passive device that can be used to protect front end receivers and amplifiers from high power interfering signals. It is designed to selectively limit incident high power signals above the device’s threshold (Pth), without degrading the noise figure at desired receive frequencies. The AtF automatically creates notches in its passband in response to above threshold signals without any prior knowledge about said high-power signals and reflects above threshold power from its input. The width and depth of these notches are proportional to how much above threshold the high-power signals are. The selectivity of the device corresponds to this notch width.
